Produced between 1948 and 1950 the 166 Inter got the first Ferrari V12 engine to reach 2-litre capacity. The model was available in both open-top and hardtop variants.
The 166 Inter was responsible for Ferrari's increase of reputation in the all-important American market and was the first to do well outside Italy. The 166 Inter models were the road versions of the 166 sports racing models like the 166 MM barchettas.
